In order to test the statistical power and the quality of the classifiers, we also test LDA with Leave-One-Out Cross Validation (LOOCV) [1]}. LOOCV is performed as follows: (1) Select a single-item as a test point; (2) Use all other points as a training set; (3) Apply the learning algorithm to training set once for each test point. The performance of the classifier with LOOCV is also evaluated using the sum of sensitivity and specificity.
